Contains two packs of 100mL each.
One of them contains 8g of Potassium hexacyanoferrate(III); the other 20g of Ammonium iron(III) citrate.
As the bottles are 100 ml, we only need to fill the bottle with distilled water (or tap water), close and shake to mix.
For best conservation, it is best to keep the two solutions separate.
These are the same liquids that the Cyanotype Kit includes.
